Efficient Mowing for Large Lawns
The Mountfield 1543H-SD is a highly capable side-discharge garden tractor, expertly designed for those with large areas of grass to maintain. Powered by a robust STIGA ST 500 single-cylinder engine with a 452cc displacement, this machine delivers consistent and reliable power for tackling lawns up to 3 acres. The electric key-start ensures hassle-free operation every time.
Advanced Cutting System
At the heart of the 1543H-SD is its impressive 108cm (42″) twin-blade cutting deck. As a dedicated side-discharge model, it is particularly effective on longer grass, neatly cutting and dispersing clippings to the side where they can break down naturally. For those wanting to fertilise their lawn as they mow, an included mulching plate finely chops the clippings and returns them to the turf, providing valuable nutrients. Blade engagement is handled electronically for safety and convenience. A simple lever allows the operator to select from seven cutting heights, ranging from 25mm to 80mm, ensuring a perfect finish for any condition.
Superior Control and Comfort
Driving the 1543H-SD is a pleasure thanks to its pedal-operated hydrostatic transmission. This functions much like an automatic car, providing smooth, infinitely variable speed control in both forward and reverse without the need for manual gear changes. Operator comfort is further enhanced by the Mountfield ergonomic steering wheel and classic adjustable seat. Practical features include conventional headlights for visibility, a front bumper for protection, a storage compartment, a cup holder, and a washing link for easy deck cleaning. The pivoting front axle and two anti-scalp wheels help the deck follow the contours of the ground, preventing turf damage on uneven lawns.
A tow hitch is included as standard, increasing the tractor’s versatility, while an optional battery charger is available separately. This machine also comes with a 5-year extended manufacturer’s warranty (subject to terms and conditions).

Frequently Asked Questions
Who is the Mountfield 1543H-SD best suited for?
This garden tractor is ideal for homeowners with large lawns, paddocks, or orchards up to 3 acres (approximately 6000 m²). Its side-discharge function makes it particularly effective for managing longer, thicker grass where collection is not required or practical.
What is the main advantage of a hydrostatic transmission?
A hydrostatic transmission offers a significant advantage in ease of use. It is operated by a foot pedal, similar to an automatic car, allowing for smooth and precise adjustments to your speed without needing to stop and change gears. This makes manoeuvring around obstacles like trees, flowerbeds, and garden furniture much simpler and more intuitive.
Does this tractor come with a mulching kit?
Yes, the Mountfield 1543H-SD includes a mulching plate as standard. This allows you to easily switch from side-discharging to mulching, where grass clippings are cut into fine particles and returned to the lawn. This process acts as a natural fertiliser, promoting a healthier, greener lawn.
What does the ‘Ready to Mow’ service from an authorised dealer involve?
When you purchase from an authorised Mountfield dealer like Sims Garden Machinery, you receive a machine that is fully assembled and inspected. For local customers, our service includes a thorough Pre-Delivery Inspection (PDI) by our qualified mechanics, personal delivery, and a full demonstration of the machine’s features and safety functions, ensuring it is genuinely ready to mow upon arrival.
